The presentv invention relates to track liners or jacks. y

An object of the, invention is to. provide an instrument for adjusting arail later- .Ahother object of'the'invention is to provide a devicewhich can be operated ,to accomplish the lifting and proper positioningof a. track rail with a minimum of labor andefort.

Still another object is to providea clevice for this .purpose whichshallliave a movable foot, by which shifting of the rail will befacilitated, and which will eliminate the necessity of providing prongsor other means on the base plate to prevent its slipping on the ballastand sliding out from under the rail.

A further object of the invention is to provide such a devicewhich issimple in construction and easy to operate, and in which the effort ofthe operator is not wasted by. unnecessary friction between the arts.

Still further objects and adv-antaes of the invention will be apparentfrom the following description taken in connection with the accompanyingdrawings, 4which illustrate a preferred embodiment ot' the invention,and in which:

Fig. 1 is a side elevation showing the operating lever in partlyraisedposition;

Fig. 2 is a top plan view of Fig. 1;

Fig. 3 is a side elevation, partly in sec-- tion, showing the operatingarm'in its lowered position.

'Figa 4 is a fragmentary side elevation, partly in section, showingthemovable foot of Vthe operating lever.

Fig'. 5 is a sectional elevation showing the movable foot of theoperating lever,

and taken onktheline 5-5 of'Fig. 2.

Referring in detail to the drawings, in

which like reference numerals indicate like parts throughout,theembodiment of the invention here shown comprises a base plate 1,

1- which may conveniently be of suitable metal and rectangular in form,as shown;l

Near one end of the base plate is located a mounting plate or movablefoot'2, pro# vided with lugs 3 through which a bolt 4 passes pivotallysecuring the operatin lever 7 to the movable foot 2. The movab e foot 2is retainedin sliding contact with the base plate 1 by any suitablemeans'such as the side guide plates 5 and 5 secured to the base plate 1by suitable means such as the screwbolts shown, and movement of themovable. foot 2 forwardly and rearwardly on the base plate 1 may belimited by the stop bolts 6. The mounting plate 2 thus forms a movableor sliding foot for .the operating lever 7.

The operating lever 7 may conveniently tak@ the form illustrated in thedrawings, and be provided at its free end with a socket 8, designed toreceive a wooden or other lever, preferably several feet in length, toincrease the length of the lever arm, and thereby facilitate theoperation of the track liner. .The track engaging lever is shown asbeingvconstructed of two side plates 9 and 10, spaced apart and'embracing between them at one end the operating` lever 7, to which theside plates 9 and 10 are pivotally attached by the pivot bolt l1. The toedgesof Vthese side. plates form the 'trac engaging portion of theliner.

The other ends of the track engaging lever are free, and carry betweenthem the antifriction roller 12, mounted between said side plates on thebolt 13, upon which the roller 12 is freely rotatable. The diameter ofthe roller is such, in relation to the. side plates, thatthe bottom ofthe roller extends below the lowermost portion of the side plates andcontacts with the top surface of the base plate, upon which `it may rollwhen the track liner is being operated.

A strap or stop 14 may be secured to the base plate, forexample, by thebolts 15, and include between its ends the roller 12, embracing saidroller and passing over it between the side plates 9 and 10. The Strap14 is shown as being, substantially, of iniferted U-shape, and there issuicient space between the arms of the U to ermit considerable movementof the r,ol er 12 back and forth on the base plate.- The strap `14 alsoacts to prevent the track enga 'ng pactand easier to transport.,

'- struction there has been provided a track In o eration, the trackliner is bro ht up to t e rail on-the side away from whichv -it iste bemoved, until the track engaging lever contacts with the rail'. A woodenor other lever may then be conveniently insorted inthe socket 8 and usedto raise the f voperating lever' I about its pivot on the mounting plateor movable foot 2. The

-' is so constructed vthat it has just enough i onv the ballast.

-on the surface bearing on the base plate to slide thereon whensuilicient power is put on the operatin lever before thebase plate slipsallast, and thereby prevents the liner from slipping out from undertherail. The sliding of lthe movable foot on the base late also makes itpossible to use a smooth Ease late, that is, one without any prongs oroter means to prevent its slipping back The rol-ler 12 eliminates frictionbetween ,the track engaging lever andthe base plate, and is preventedfrom moving oil the base plate by the strap 14.

It will be seen that by the foregoing conliner byv which nthe rails of atrack may easily and quickly be shifted, and one which may readly becarried about and brought into position and be operated ciiciently bya'minimum of labor; and that the operating parts areall slidable on asmooth surface which. forms a part of the track liner. -It will also beobserved that friction is deoxeased by lifting the rail as well asshifting it, and that due to the sliding movement of the .movable foot,the buse plate remains in. a steady position on the ballast, no prongsor other means being needed to steady it.

What is claimed is: Y 1. A 'track liner comprising a base plate,

'an operating lever pivotally associated therewith and having a footlongitudinally slidable thereon, and a track engaging lever having `oneend pivoted to said operating lever and having its other end movablyassociated with said base plate. 2. A track liner comprising a baseplate an operating lever, a movable foot for 'said operating leverlongitudinally slidable on said base plate, said o rating lever-be'pivcted to said movab e foot, and a tra engaging lever pivotallyassociated .with 'said operating lever. i

3. A track liner'comprising a. base plate,

rising a hase late, a movable foot longitu lnally slidable t ereon anoperating lever. pivoted to said movable foot, and a track engaginglever comprising side plates embracing at one end said operating lever`and pivoted thereto, and having at its other end an antifriction roller.movable on said base plateg v 5. A trackliner comprising a haseA late, amovable foot longitudinally slidab e` on said base plate, an operatinglever pivotall associated with said movable foot, s. trac engaging leverhaving one end lplvoted to operating lever pivotally associatedtherewith and having a lower portion loni said operating leverand itsother end movable on said base plate, ing said movable foot and limitingits movement thereon.

6. A track liner comprising a base late, a movable foot longitudinallyslidab e on said base plate, an operating lever pivotall associated'withsaid movable foot, a trac engaging lever having one end pivoted to saidoperating lever and' an antifriction bearing roller at its other endmovable on and means for guidon said base plate' said base plate, meansfor limiting themovement of said movable foot on said base plate, andmeans fcrlimiting the movement' of said antiriction bearing roller on'said base. plate.
